+## Films selection with a twist
+
+Site: Codewars\
+Difficulty per Site: Medium
+
+## Problem
+
+For this task we need to get film_id, film title and length from the `film` table in the DVD rental database, but with a twist: we need to exclude films with a length between the minimum length of R-rated films and the median length of `PG-13` rated films. This means that the selected films will be either strictly shorter than the shortest R-rated film or strictly longer than of median length `PG-13` rated film [[Full Description](https://www.codewars.com/kata/644424f8d7bab510f1375d20)]
